I'm trying to stream video content from my 323 to my 360 using Twonky v.4.2.1 but even though I can't get the videos to show up on the 360 - I either get a 'No Video Files Found' if I share a single directory which definitely contains a WMV (a WMV file which plays if I stream it from my desktop to the 360) or if I share the entire drive I get a whole series of what look like directory names which a red can't access symbol. The names seem to be based on the ID3 tags of some MP3s I have on the drive.

Does anyone have any thoughts on why this might be? I'm really frustrated - I just want to watch a movie without having my desktop on all the time!

Can see Twonky from 360
Can log into Twonky from browser but only very, very intermittently.
Can go into directories on 323 from 360 but only after several attempts - most of the time it says connection lost.
